Kacper ,

thank you for your time. I have sound but sometimes after playing a
youtube video music stops playing from totem, etc. Below is what I am
doing and what the "problems" are.

### Load additional modules from GConf settings. This can be configured with

### Please keep in mind that the modules configured by paprefs might conflict

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

### Automatically restore the volume of streams and devices
load-module module-device-restore
load-module module-stream-restore

### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)

.ifexists module-hal-detect.so
load-module module-hal-detect tsched=0
.else
### Alternatively use the static hardware detection module (for systems that
### lack HAL support)
load-module module-detect
.endif

### Automatically load driver modules for Bluetooth hardware
#.ifexists module-bluetooth-discover.so
#load-module module-bluetooth-discover
#.endif

### Load several protocols
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif

### Network access (may be configured with paprefs, so leave this commented
### here if you plan to use paprefs)
#load-module module-esound-protocol-tcp

#load-module module-zeroconf-publish

### Load the RTP reciever module (also configured via paprefs, see above)
#load-module module-rtp-recv

### Load the RTP sender module (also configured via paprefs, see above)
#load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 
description="RTP Multicast Sink"
#load-module module-rtp-send source=rtp.monitor

### Automatically restore the default sink/source when changed by the user 
during runtime
load-module module-default-device-restore

### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams

### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink

### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.
load-module module-console-kit

### Enable positioned event sounds
load-module module-position-event-sounds

# X11 modules should not be started from default.pa so that one daemon
# can be shared by multiple sessions.

### Load X11 bell module
#load-module module-x11-bell sample=bell-windowing-system

### Register ourselves in the X11 session manager
#load-module module-x11-xsmp

### Publish connection data in the X11 root window
#.ifexists module-x11-publish.so
#.nofail
#load-module module-x11-publish
#.fail
#.endif

### Make some devices default
#set-default-sink output
#set-default-source input
